Program Scope

This Certification Program applies to Production Models of 50 and 60 Hz VRF Systems that meet the following criteria:

  • Include multi-split system air-conditioners and heat pumps irrespective of their type of electric power source, or secondary fluid (e.g. air-to-air or water-to-air) with cooling capacity equal to or above 65,000 Btu/h for Air-Source systems and all cooling capacities for Water-source systems.
  • Use distributed refrigerant technology with cooling and heating capacities for Outdoor Units up to 760,000 with Indoor Units from 5,000 Btu/h [1,462 W] to 144,000 Btu/h [42,202 W]. Each indoor unit is designed to condition a single zone;
  • Consisting of the following matched components: a) an Outdoor Unit with single or multiple compressors or variable capacity compressor; b) multiple Indoor Units; and c) a zone temperature control device.
